Commando told the Daily Telegraph that the kids love spending time together.

“It’s great, my eldest can find it a bit challenging at times,”

“She’s almost playing the big sister and babysitter which helps us a lot, we can sit down with a cup of tea and she will get on the computer and they’ll all run over and start watching that together, but they all connect as kids do though.”

Willis and his fitness guru partner, Michelle Bridges, 46, have been raising their son Axel and didn't appear in the last series of The Biggest Loser.

When asked about a return to the show on the red carpet of InStyle Women of Style Awards, Bridges didn't rule anything out.
